### How to push multiple flows to the controller at once

Hi everyone. This problem is driving me nuts: I have an external controller (out-of-band) conneted to a local hypervisor where running Open vSwitch with a vmbr0 bridge.

When I manually add the following flows to Open vSwitch, it works like expected and the switch redirects traffics like a charm:

ovs-ofctl add-flow vmbr0 priority=20000,ip,nw_dst=10.30.5.1,actions=NORMAL (
ovs-ofctl add-flow vmbr0 priority=15000,ip,nw_src=10.30.5.0/24,actions=strip_vlan,output:9


But I want to control the bridges from ODL but I haven't been able to figure out how to send these flows at once to the ODL controller by using postman because if I send the first one it gets stored at CONFIG but when I send the second, then the first one gets deleted and remains only the last one.

This is the way I am sending the flows to this URL: http://controller:8181/restconf/config/opendaylight-inventory:nodes/node/openflow:1

FLOW1:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<node xmlns="urn:opendaylight:inventory">
<id>openflow:1</id>
<table xmlns="urn:opendaylight:flow:inventory">

</flow>
</table>
<pass-through xmlns="urn:opendaylight:netconf-node-inventory"/>
</node>


FLOW2:

<?xml version="1.0"?>
<node xmlns="urn:opendaylight:inventory">
<id>openflow:1</id>
<table xmlns="urn:opendaylight:flow:inventory">

<priority>15000</priority>
<match>
<ipv4-source>10.30.5.0/24</ipv4-source>
<ethernet-match>

</ethernet-match>
</match>
<flow-name>FLOW2</flow-name>
</flow>
</table>
<pass-through xmlns="urn:opendaylight:netconf-node-inventory"/>
</node>


The first flow gets deleted from http://controller:8181/restconf/config/opendaylight-inventory:nodes/node/openflow:1/

What am I doing wrong?

Thank you very much
